To all whom imag-concern:

Be it known that I, PAUL I1. PFIJAGER; a

' citizen of the United 'States of numerica, and

resident of Chicago, Cook county, Illinois;- have invented a certain newanduseflrl'lm prominent in Axle-Generator Supportsyoi which thefollowing is a'specification.V

My invention re'latesto improved meansr Cnc of the objects of myinvention is to" provide a support in which-'these wearing parts arereduced to' a minimum, andl in which the vsupporticonsists of al singleintegral casting secured to the frame' of the' car truck. These andother objects of'nry involition will vbe more clearly understood byhaving reference to the accompanying 'di-aw# ings in which I haveillustrated one embodiment of my invention, although, of course,`

it will be understood that'my inventionv is not liinitedtotheparticularshape and form oil the casting shown in these-drawings, butthat .f'arious modilications can bem'ade and still come within' thescope ofiny invention.

Figure 1 is aplan* view of my improved support. Fig. 2 is a sectionalView taken* on the line 2 2 in Fig. 1.. Fig.: 3 is an end View' of thedevice. Fig. 4 is a detailed side View of' the frame. Figs. 5 and Garedetail viewsi I represent a portion5 of the frame` of the frame consistsof the 'side sill 9 and theinter mediate longitudinal braces 10'fand'115 In the usual construction the end sill dips" downward, as indicatedin Fig.j 3, and'the car axle is supported in suitable bearingsl hungfrom the side" frames, as indicated in Fig. 2.

In the usual construction the axle generator is located outside of theend sill and driven by a belt on a pulley on theca'raxle' In order to somount the generator, I provide an integral casting 13 whichis'rectangular in shape, as shown in Fig. 1, and also dips downward,.asshown in Fig. 4.' This casting is provided with two supportingextensions 14 andl, -which are' securely bolted zto the intermediatebars 10 and 11. As shown, these arms are setinward to a slight degree,this being forth'ereason that it is necaessary forv the castingAtocle'ar the brake re'- llease springs 16. Of course, if these springswere set inwardfarth'er' on-the end sill, it vioirld'notbe necessary'to' oiset'the casting `infthis manner; Connecting the two lowerhorizontal side-sections of thiscasting area fpair ofbra-ee bars 17and'lS. hese side members of the casting are provided with.rectangu'l'a-r' openings 19' within which are llocated alinin'g' blocks20.- These alining blocks are provided withia Central portion ywhichprovides a bearing 21 for the rock shaft22-.- These spacing blocks are'secured to the casting 13 `by means ofthe bolts and. nuts 23. Thek axle'generator 24 is mounted upon'thisfrock shaft 22v in the well knownmanner, being provided with a pair of down iwardly extending legs 25through which the rock shaft 22" passes." The generator pulley 26 isconnected witht the axle pulley 27 by :means 0I' the belt 28,Whereby'power is transinitted from the' axle to the generator. In orderto properly aline-the generator pulley with the axle-pulley it' ismerely necessary to properly adjust the alinement blocks 20 withinthe-fran'1e'-l3.y Inorder to mount the generator securely upon this rockshaft 22, I provide any suitabley means, such as a tension rod 30 whichpasses through an opening 1n thecastin'g 31 carried by therearconnectiiigbar of the supporting castingand is secured atits forward endt0 the frame of the axle generator. A spring 32 is mounted on this rod,and this rod is threaded and provided with 'a'n adjustable nut 33 whichbears against the spring, whereby on tightening this `nut the generatorcan be' rocked back Ward so as to tighten the bolt 28, While when thenutis' loosened the spring: tension Jforces the generatory in theopposite direction to loosen the belt.

IVhil'e I have-shown' one particular means 'for holding the generator inplace on the rock-shaft, it-is, of course'7 understood that anysuitablemeans can be employed for this purpose: v

In order'to makea more rigid connection 4between the support 13 and thecar truck frame, I provide an-ofset portion 29'which is adapted toextend beneatlrtlie end sill 9` and thus grip the same, and in thismanner providing a very rigid and eflicient support for the axlegenerator.

It will thus be seen that I have devised a very simple supportcomprising a single i'ntegral casting, and in which substantially allthe wearing parts are eliminated. The only wear would occur on thebearing for the rock shaft 21 in the alinement blocks 20,

and in the usual construction a bushing is provided which surrounds thisshaft whereby the entire wear comes on this bushing.

While I have illustrated and ydescribed one particular embodiment of myinvention, it will be understood that I do not wish to be limited to theexact construction shown and described.

What I claim as my invention is:

1. In a car truck, a frame, an axle generator, and a support for saidgenerator carried by said frame, saidsupport consisting of a `singleintegral casting independent of saidh frame.

2. In a car truck, a frame, a single integral casting secured t0 saidframe, a rock shaft mounted in said casting, andan axle generatormounted on said rock shaft, said casting being independent of saidframe.

3. In a car truck, a frame, a single integral ,casting secured to saidframe, a rock shaft mounted in said casting, an axle generator v mountedon said rock shaft, and means for adjusting the position of said rockshaft in said casting to properly aline said axle generator, saidcasting being independent of said frame.

4. In a car truck, a frame, an integral casting secured to said frame,said casting comprising a pair ofmembers spaced apart, downwardl curvedand longitudinally extending si e members, an end member extendingbetween said side members, a rock shaft carried by said frame, and anaxle generator carried by said rock shaft.

5. In a car truck,a frame comprising side members and an end sill anaxle generator support secured to said frame, said support comprising apair of supporting members secured to said frame, downwardly andrearwardly extending side members, brace bars y securing said sidemembersl together, a rock shaft mounted in said side members, and anaxle enerator mounted on said rock shaft.

6. n a-cartruck, a frame comprising side members and an endv sill, anaxle lgenerator support secured to said frame, said sup` port comprisinga pair of supporting members secured to said frame, downwardly andrearwardly extending side members, brace bars securing said Side memberstogether, a rock shaft mounted in said side members, an axle generatormounted on said rock shaft, and means for adjusting the position of saidrock shaft in said side members.

7. In a car truck, a frame, an axle generatorsupport secured thereto,said support comprising side members spaced apart and secured at theirends to said frame, said members extending downwardly and rearwardly,and provided with an extending lug for gripping said end sill, and ashaft carried by said members, and an axle generator support mounted onsaid shaft.

8. In a car truck, a frame, an axle generator support secured thereto,said support comprising side members spaced apart and secured at theirends to said frame, said members extending downwardly and rearwardly andprovided with an extending lug for gripping said end sill, a shaftcarried by said members, an axle generator support mounted on saidshaft, and means for adjusting the position of said shaft in saidmembers. f

9. In a car truck, a frame comprising side and end sills, an axlegenerator support secured thereto, said support comprising an integralcasting consisting of a pair of spaced side members, an end memberconnecting said side members, said side members extending downwardly andprovided with a notched portion adapted to grip the end sill, means forsecuring said casting to the frame, and an axle generator supported insaid casting. v

10. In a car truck, a frame comprising side and end sills, an axlegenerator support secured thereto, said support comprising an integralcasting consisting of a pair of spaced side members and an end memberconnecting said side members, said .side members extending downwardlyand provided with a notched portion adapted to 'grip the end sill, meansfor securing said casting to the frame, a rock shaft mounted -in` saidcasting, an axle generator mounted onv said rock shaft, and means foradjusting thel position of said rock shaft in said support.

11 In a car truck, a frame, an integral casting 'secured to said frame,said casting comprising a"pai-r.of members spaced apart,

`downwardly curved and longitudinally extending side members, an endmember extending between said side members, and an axle generatorsupported by said integral casting.
